To all whom it maycovwern:

Be it known that 1, JOHN M.-DAHLBURG, a citizen of the United States, residin at Atlantic, in the county of Cass and gtate of Iowa, have invented certainnew and useful Improvements in Doubletrees and I do hereby declare the following to be a full, clear, and exact description of the-invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in a double-tree and has for one of its objects the provision of a device of this character, whereby the double-tree will be held from tilting forward on the tongue, thus preventing wear of the tongue and other parts associated therewith.

Another object of this invention is the rovision of a supporting structure secure to the tongue and adapted to pivotally. support the double-tree upon the tongue and which will prevent the double-tree fromv tilting forwardly or rearwardly during use.

A further object of this invention is the provision of a pair of plates secured to the tongue and having their ends relatively spaced to receive a substantially U-shaped hanger carried by the double-tree, whereby the double tree is pivotally supported on the tongue.

A still further object of this invention is the provision of a double-tree of the above stated character, which shall be simple,

durable and efficient, and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists of cerv tain novel features of construction, combination and arrangement of parts hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing,

- in which Figure 1 is a longitudinal sectional view of a double-tree constructed in accordance with my invention,

Fig. 2 is a fragmentary perspective view of the same.

Referring in detail to the drawing, the numeral 1 indicates a tongue having the usual bow 2 secured to one end and to which is adapted'to be connected the vehicle. This tongue is especially adapted to be used in connectlon with light vehicles, such as buggies, carriages andthe' like, and the tongue has secured to its under face, reinforcing T-shaped strip 3, which has its T-shape'd end secured to the under face of the bow 2 as illustrated at 4. The aforedescribedstructure relates to a well known construction of tongue and to which my invention is applied. V v

v A pair of relatively spaced plates 4 and 5 are secured to the upper face of the tongue 1 by the bolts 6, which secure the bracing strip 3 to the tongue. Upon one end ofthe Imembers 4 and ,5 are horizontal head porend is bent upwardly and disposed in a plane abovethe tongue as illustrated at 8, and has its free end portion apertured to receive the bolt 9. The member 5 is increased in width as. shown at 10 and has formed thereon, downwardly depending lips 11, which engage the Side faces of the tongue for strengthening the tongue and aiding in securing the member 5 to the tongue. The member 5 at its increased portion in width as shown at 10 is bent at right angles to form a vertically disposed supporting mem ber 12, which has its upper end bent at right angles as illustrated at 13 for supporting the portion 8 of the member 4. A downwardly and forwardly extending extension 14 is formed upon the right angled end 13 of the supporting member 12 and is spaced from the portion 8 of the member 4 to receive a substantially U-shaped hanger 15, which is or otherwise secured to a double-tree 16 as illustrated at 17. The double-tree 16 is of the usual construction and has pivotally secured to each end, the swingle trees 17 to which the draft animals are hitched.

The substantially U-shaped hanger 15 being pivotallv secured to the members 4 and 5 supports the double-tree 16 over the upper tar erriou,

face of the-tongue and will prevent the double-tree from tilting forwardly and rearwardly during use.

From the foregoing'description taken in connection with the accompanying drawing, it Will be noted that the necessity of making a hole in the tongue for securing the double-tree 16 thereto, is obviated, and it also maybe noted that the device may be readily and conveniently applied to the tongue now in use. c

, While I have shown and described the preferred embodiment of my invenion, it will be understood that minor changesin construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invenion, What Iclaimis: v V

A Wagon tongue attachment comprising upper and lower plates secured one above the other to the top face of the tongue and extending rearwardly fromthe double tree of the tongue to the bow, means connecting the rear ends of the plates to the bow, said upper plate having its forward portion inclined upwardly and having its forward end disposed in a plane above, the tongue and parallel therewith, said lower plate having its forward portion bent vertically and horizontally, and the horizontal portion disposed against the forward portion ofthe upper plate to support the same and limit its downward movement, an angularly related extension formed on the horizontal portionf of the lower plate and spaced from the free end of the upper plate and the tongue, and a clamp pivoted between the free end of the upper plate and the extension and. secured tothe double-tree so that said double-tree is located between the extension and the JOHN M. DAHLBURG.
